The Mobile Winder SBN FH-55 and the Development of the SBN FH Series

Top priority of occupational safety is precautionary measures and the avoidance of accidents. But fast, innovative and, above all, well-prepared rescue measures are just as essential in mine rescue. The rescue concept for each shaft provides an auxiliary hoisting for men rescue in case of emergency. Mines with shafts located at a greater distance from each other, have to provide an auxiliary hoisting system for each shaft. Such an auxiliary hoisting system was developed as part …

Rehabilitation of Shafts – Current Examples of Executed Solutions on Salt and Potash Mines

Due to the shaft itself and the use of the shaft specific conditions arise for the rehabilitation of old shafts. The shaft construction companies have to face these circumstances again and again when planning and carrying out the work. Almost always the influences of water and/or rock pressure determine the day-to-day work of these companies. Three case studies of shaft rehabilitation carried out …

Reconstruction and Qualification Work at Konrad 1 Shaft

In many areas where hydraulic fluids are used, it is important to minimize the fire hazard that can be caused by hydraulic fluids. Whether in steelworks and power stations or in machine tools or underground mining, it may be necessary to use hydraulic fluids with improved fire engineering properties, so-called flame-retardant hydraulic fluids, in order to prevent the formation and spread of fire. These properties must be tested and certified by independent test laboratories. Therefore, standards for testing these properties were introduced, which have since created a high level of safety.

Categories of Gas Outbursts in Hard Coal Mining from a Practical Point of View

The term “gas outburst” is in use worldwide for a variety of types of sudden emission of big volumes of mine gas, at which a differentiation concerning the causes of their occurrence is not carried out in many cases. As a consequence, it is often not possible to analyse the causes of these events in the different mining regions in the world, and to compare the effectivity of measures for controlling the dangers. Based on the findings and experiences in German hard coal mining …

Physically Preventing Dust Emissions at Conveyor Belts and Belt Transfers

Many solutions have already been developed to prevent dust emissions at special sections of conveyor belt systems and at transfer points. All measures taken for this purpose serve to protect the people working in the surrounding area, to keep the production environment clean and often to provide explosion protection. However, most of the classic dust prevention methods also involve risks and side effects such as increased wear and tear, causing plant operators to face different problems.

Enhanced Safety and Efficiency through Active Light

The demand for raw materials is increasing worldwide. The reasons are a growing world population and the resulting increase in energy requirements. Mineral or metallic raw materials are needed for an increasing number of electronic devices such as mobile phones, headphones and batteries. The global energy transition also will not make progress without rare earth elements or metals such as aluminum, iron or copper. The market potential is enormous and so is the importance of open-pit mines through which these raw materials are extracted. Mine operators are faced with challenges in terms of safety and productivity.
